  • Position tracking and imaging system for use in medical applications
    Patent number: 5803089
    Abstract: A system is disclosed for monitoring the position of a medical instrument with respect to a patient's body and for displaying at least one of a plurality of prerecorded images of said body responsive to the position of said medical instrument. In one embodiment the system includes a reference unit secured from movement with respect to the patient's body such that said reference unit is substantially immobile with respect to a target operation site. The system also includes a remote unit for attachment to the medical instrument. A field generator may be associated with one of the units for generating a position characteristic field in an area including the target operation site. One or more field sensors may be associated with either of the units responsive to the presence of the position characteristic field for producing one or more sensor output signals representative of said sensed field.
    Type: Grant
    Filed: September 13, 1995
    Date of Patent: September 8, 1998
    Assignee: Visualization Technology, Inc.
    Inventors: Maurice R. Ferre, Peter D. Jakab, James S. Tieman
